Turn obstacles into opportunities with a smarter path to certification

By Melissa McCoy, Chief Information & Security Officer – CISSP-ISSAP, CCSP, RP

Preparing for a Cybersecurity Maturity Model Certification (CMMC) assessment is a complex process with numerous potential pitfalls that can delay certification, increase costs, or even result in a failed audit. CMMC Compliance: Avoiding the 7 Deadly Pitfalls helps you pinpoint common missteps, take decisive action, and streamline your path to certification.

1. Inadequate Scope Definition:

This is one of the most fundamental and frequent mistakes. Companies often fail to accurately identify and define the “CMMC Enclave”—the systems, networks, and assets that store, process, or transmit Controlled Unclassified Information (CUI).

• The Pitfall: Over-scoping your environment leads to unnecessary work and costs by forcing you to apply CMMC controls to systems that don’t handle CUI. Under-scoping, on the other hand, leaves sensitive data unprotected and will result in a failed audit.
• How to Avoid It: Conduct a thorough data flow mapping exercise. Trace exactly where CUI enters your organization, how it moves, where it is stored, and who has access to it. This allows you to create a clear and defensible CMMC boundary.

2. Treating CMMC as an IT Problem:

CMMC is not just a technical checklist for the information technology (IT) department. It requires a holistic, organization-wide approach to security.

• The Pitfall: Delegating CMMC preparation solely to the IT team. This overlooks critical components, such as policies, processes, and employee training, which are significant parts of the framework.
• How to Avoid It: Get buy-in from senior leadership and form a cross-functional team that includes representatives from IT, HR, legal, and other relevant departments. CMMC is a business priority, not just a technology project.

3. Insufficient Documentation:

In CMMC, “if it isn’t documented, it didn’t happen.” Assessors don’t just want to see that a control is in place; they need to see evidence that it’s implemented and operating effectively.

• The Pitfall: Neglecting to create or update key documents like the System Security Plan (SSP), Plans of Action & Milestones (POA&M), and all related security policies and procedures. Many companies also fail to collect objective evidence of their practices, such as audit logs, emails, meeting minutes, system screenshots, access reviews, and training records.
• How to Avoid It: Start a documentation strategy early. Create a System Security Plan that details how each CMMC control is met. Ensure all policies and procedures are clearly written and consistently followed. Implement a system for collecting and storing evidence/artifacts on an ongoing basis, not just immediately before the assessment.

4. Waiting Too Long to Start:

Achieving CMMC compliance, particularly at Level 2, is a long-term project that can span several months or even exceed a year.

• The Pitfall: Believing you can achieve compliance quickly. Many companies wait until they receive a contract with a CMMC requirement, only to realize they are months behind schedule and will not be eligible to bid.
• How to Avoid It: Be proactive. Start your CMMC journey as soon as possible, even if you don’t have a contract with a CMMC clause. Conduct a readiness assessment (gap analysis) to understand your current security posture and create a remediation plan.

5. Neglecting Supply Chain and Third-Party Risk:

Your CMMC posture is only as strong as your weakest link. If a subcontractor or service provider handles CUI on your behalf, they must also be CMMC compliant.

• The Pitfall: Failing to assess and manage the cybersecurity risks posed by vendors and suppliers. You are responsible for ensuring your entire supply chain is secure.
• How to Avoid It: Develop a third-party risk management plan. Require your subcontractors to meet the same CMMC level you do and verify their compliance. Review contracts to ensure they include cybersecurity requirements and the right to audit.

6. Lack of Employee Training and Awareness:

Human error remains a leading cause of security incidents. CMMC requires a trained and aware workforce.

• The Pitfall: Assuming employees understand their role in cybersecurity without providing formal training. A single employee clicking on a phishing link can compromise your entire system.
• How to Avoid It: Implement mandatory and regular security awareness training for all employees. This should cover topics like phishing, social engineering, password hygiene, and proper handling of CUI. The training should be tailored to the specific roles and responsibilities of your staff.

7. Over-relying on Technology Alone:

Simply buying new security software or tools is not enough. CMMC requires that these tools be correctly configured, monitored, and supported by robust policies and procedures.

• The Pitfall: A “check-the-box” mentality where a company purchases a tool but doesn’t correctly implement it or ensure it’s integrated with their processes. For example, assuming that storing CUI in a FedRamp-certified cloud provider is all that needs to be done.
• How to Avoid It: Technology alone won’t solve your problems. Trained personnel, documented and operationalized processes, and administrative controls are needed.

Now is the time to take action. By addressing these challenges early, you can sidestep costly mistakes and build a cybersecurity program that is both resilient and audit-ready. CMMC Compliance: Avoiding the 7 Deadly Pitfalls isn’t just about passing an audit; it is about turning obstacles into opportunities with a smarter path to certification. The sooner you begin, the greater your chances of achieving compliance on the first attempt and staying competitive in the contracting space.
